This is a wide cultivated valley with a number of small parcels of woodland, the settlement of Thackthwaite lying nearest to the fell.

To the west are a number of small streams including Mosser Beck and Cat Gill, which also flow northward and ultimately join the Cocker.

North of Fellbarrow is the lower top of Hatteringill Head (1,263 ft), listed in some guidebooks[2] before the ridge falls away over Whin Fell to a minor road known as Mirk Lane.

[3] The summit is a gently curving grassy dome, crossed by a fence, and sports an Ordnance Survey triangulation column and a cairn.

To the east is a fine view of the North Western Fells across Lorton- the Whiteside - Grisedale Pike ridge perhaps the highlight- with Skiddaw and Blencathra popping up behind.

Further round the view is crowded with fells, the northern wall of Ennerdale seen side on throughout its length and backed by Pillar and the Scafells.
